Arranging child care is like fiddling with one of those rigid fun-with-shapes puzzles.And your needs most resemble a rhomboid.Thankfully, Fun Club, a fully licensed child care center, is flexible. All week long (Monday through Thursday) the doors are open from 7 a.m. to 10 p.m.; Friday and Saturday nights they keep it rocking until 1 a.m. (Date night, anyone?)During the day, age-appropriate activities (learning numbers and letters, painting) are organized by certified preschool instructors. Weekend fun includes movies, karaoke, carnivals, yoga, and chess tournaments for kids ages 2 to 12.Plus, drop-ins are welcome.For convenience, there’s just no parallelogram.Fun Club, 6710 Southwest 80th Street, South Miami (305-669-1700 or funclubkids.com).
